IMPROVEMENT IN STRETCHERS FOR FORMING SWELLS 0R ENLARGEMENTS IN THEUPPERS 0F BOOTS AND SHOES.

Specification forming part of Letters Patent No. 2] 0,285, datedNovember 26, 1878 application filed September 25, 1878.

To all whom "it may concern Be it known that I, JOSEPH J ADGATE, of NewYork, in the county of New York, and in the State of New York, haveinvented certain new and useful Improvements in Stretchers for FormingSwells or Enlargements on Boot and Shoe Vamps; and do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangementof a device or stretcher for forming swells or enlargements on boot andshoe Vamps, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a side view of my invention. Fig. 2 is an end view of thesame.

A and B represent two metal arms or jaws, the inner ends of whicharecurved, as shown, halved together, and then united by arivet, a, whichallows said jaws to open and close sufficiently far for the purposesintended. The rivet a is preferably cast with one of the jaws in onepiece, while the other jaw has a hole for the passage of the rivet.

On the end of the jaw A is formed a fork, O, and in said fork isjournaled a male die, D, having four faces, (more or less,) and on saidfaces are protuberances a a, of different sizes and shapes.

The end of the jaw B is formed with a groove at b, and in the same isplaced an arm, F, having a fork, G, formed on its inner end, and on itsouter end is a shoulder, f, to form a stop for its movement. The bar Fis held in the groove Z) simply by means of an eccentric-lever, L,pivoted to the side of the jaw B, and which eccentric is to work againstthe shoulder formed by the fork, to force the same inward. In the fork Gis journaled a female die, I, having the same number of faces as themale die D, and has in its faces cavities or depressions (1,corresponding in size and shape with the protuberances a of the maledie.

The object of my invention is to stretch a boot or shoe at any point,and just at the point only where needed, such as to give room for corns,bunions, 850.; and the operation is as follows: After selecting whichface upon the male die D will best answer the purpose, according to thesize and shape of the swell wanted, said die is turned with such faceinward, and this die then held by a pin, h, as shown. The jaw A, withthe male die D, is then inserted in the boot or shoe, bringing the dieto the spot where wanted. The jaw B is then closed on the outside of theboot or shoe, the female die I being turned so as to bring thecorresponding depression (1 against the outside. A ring, H, pivoted toone of the jaws, is then thrown over the jointed end of the instrument,and, by means of the lever L, the bar F is forced inward, when theleather will be stretched by the male die into the female die and formthe desired swell on the boot or shoe. It will thus be seen that Istretch only that portion of the boot or shoe where any enlargement maybe wanted, without stretching any other part.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. Two pivoted jaws, carrying,respectively, a 1n ale die, having a series of faces, and acorresponding female die, and provided with compressing mechanism, forthe purposes herein set forth.

2. The combination of a rotating male die, having a series of faces, anda corresponding rotating female die, arranged in the ends of pivotedjaws, and a compressing mechanism, for the purposes herein set forth.

3. The combination of the grooved jaw B, sliding bar F, with fork G,female die I, and eccentric-lever L with an opposing male die,substantially as and for the purposes herein set forth.

4. The combination of the jaw A, with fork 0, male die D, with pin h,the jaw B, bar F, with fork Gr, female die I, lever L, and ring H, allconstructed substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this29th day of August, 1878.
